How to perform load or performance test on wsdl web services using Jmeter.

Downlaod and install soapui and here is wsdl url: http://www.webservicex.com/CurrencyConvertor.asmx?wsdl

1. Start Jmeter
Click on Jmeter_Home/bin/ApacheJMeter.jar or jmeter.sh to open Jmeter window

2. Add 'Thread Group' under 'Test Plan'
Right-click on the Test Plan > Add > Threads (Users) > Thread Group

Number of Threads (users): The number of users that JMeter will attempt to simulate. Set the 'Number of Threads (users)' field to 10
Ramp-Up Period (in seconds): start the total number of threads. Set the 'Ramp-Up Period' field to 1
Loop Count: The number of times to execute the test. Set the 'Loop Count' field to 1.

3. Add 'SOAP/XML-RPC Request' Sampler  under 'Thread Group'
Right-click on the Thread Group > Add > Sampler > SOAP/XML-RPC Request

4. Open soap UI and create new soapui project using wsdl url as I used in below

 
5. After soap ui project created successfully. Copy soap request data as I copy below soap request.

6. Past copied soap request code into created Jmeter SOAP/XML-RPC Request” sampler in  Soap/XML-RPC data as below:

7. Add 'View Results Tree' and 'Summary Report' Listener under 'Thread Group'
Right-click on the Thread Group > Add > Listener > View Results Tree
Right-click on the Thread Group > Add > Listener > Summary Report

View Results Tree:
You can see how many request successfully serve, how many request fail to serve and it reason.
Summary Report:
    Sample - number of requests sent
    Avg - an Arithmetic mean for all responses (sum of all times / count)
    Minimal response time (ms)
    Maximum response time (ms)
    Error rate - percentage of failed tests
    Throughput - how many requests per second does your server handle. Larger is better.
    KB/Sec - self expalanatory
    Avg. Bytes - average response size
   
8. Finally Save Test plan then Press 'Ctrl'+ 'R' to run Test plan

N.B: You can change all names like as 'Test Plan', 'Thread Group', 'Sampler' and 'Listener' name
